About

The purpose of this study is to demonstrate non-inferiority of pulpotomy treatment (with new endodontic bio-materials) as a new treatment with one-visit root canal therapy as reference treatment in pain relief and clinical and radiographic success, for irreversible pulpitis of human permanent molar teeth.

Full description

In one visit RCT (Arm 1): The teeth were anesthetized, isolated and endodontic access and instrumentation of all canals was done. Canal preparation was conducted using a step-back technique. The working lengths were determined and confirmed by radiography. Sterile normal saline solution was used for intra-canal irrigation. Root canals were obturated with gutta-percha and sealer using lateral condensation technique. After placing a cotton pellet in the pulp chamber, the access cavity was closed with Cavit.

In pulpotomy treatment with CEM/MTA (Arm 2): The teeth were anesthetized. Pulpotomy procedure of removing inflamed pulp tissue to the stump level was done. Homeostasis was achieved by irrigating the cavity with sterile normal saline and application of small pieces of sterile cotton pellets. The pulpal wound was covered with an approximately 2-mm-thick layer of MTA/CEM cement. Pulp chambers were then covered with a wet cotton pellet and sealed with Cavit.
